Mortuary + Fleshtaker + Wild Cantor + Gwenom, Remorseless

Mortuary

Fleshtaker

Wild Cantor

Gwenom, Remorseless

How it works

1. Activate Wild Cantor by sacrificing it.
2. When Wild Cantor dies, Mortuary and Fleshtaker trigger.
3. Resolve the Mortuary trigger, putting Wild Cantor from your graveyard onto the top of your library.
4. Resolve the Fleshtaker trigger, causing you to gain 1 life and scry 1.
5. Cast Wild Cantor from the top of your library by paying 1 life.
6. Repeat.

This ingenious loop relies on a clever interplay of graveyard sorting and alternative casting costs to generate infinite resources. When you sacrifice Wild Cantor for mana, Mortuary swoops in to intercept the creature from your graveyard, neatly placing it right back on top of your library. Meanwhile, Fleshtaker triggers off the sacrifice to grant you life and a scry, ensuring your library's top card is properly aligned. Finally, Gwenom, Remorseless is the linchpin that allows you to bypass traditional mana constraints, letting you pay life instead of mana to recast Wild Cantor over and over again.
